That’s another viral skincare claim—and it’s misleading and potentially harmful.
The truth about baking soda and dark spots
Sodium bicarbonate (baking soda) is highly alkaline, while healthy skin is naturally slightly acidic. That difference matters a lot.
When applied to skin, baking soda can:
- Disrupt the skin barrier
- Cause irritation and redness
- Increase dryness and sensitivity
- Make dark spots worse over time (post-inflammatory hyperpigmentation)
Does it “fade dark spots”?
No solid scientific evidence supports baking soda as a treatment for:
- Acne marks
- Sun spots
- Hyperpigmentation
Any “lightening” people notice is usually from temporary irritation or exfoliation, not true fading of pigment.
What actually works for dark spots
Evidence-based options include:
- Sunscreen daily (prevents spots from getting darker)
- Vitamin C serums
- Niacinamide
- Retinoids (vitamin A derivatives)
- Dermatologist-guided chemical peels or laser treatments (for stubborn cases)
Bottom line
Baking soda is for cleaning and cooking—not skincare. Using it on dark spots is more likely to damage your skin barrier than improve pigmentation.
If you want, tell me your skin type and type of spots (acne marks, sun spots, etc.), and I can suggest a simple, safe routine that actually works.
